I'm getting exactly the same messages. Any ideas? All worked fine yesterday!

Thanks

[tortycat3]

I do not know how to fix this, could I have a hint, please? How do I install the file mentioned? Thank you.

[heygitty]

Perfect, thank you for fixing it so quickly!

[tortycat3]

Could you give me some advice as to how to implement this? Sorry but very limited programming experience.  Thanks, Eric.  Sent from Yahoo Mail for iPhone On Friday, June 5, 2020, 5:36 pm, Sergey M. <notifications@github.com> wrote: Closed #25540 via b4eb0bc. — You are receiving this because you commented.

Eric, try to update with "youtube-dl -U"

[tortycat3]

Thanks, tried that already got:

ERROR: can't find the current version. Please try again later.

Any other thoughts?

Solved it for the moment. Curl returned an invalid certificate error so I managed to use curl with the -k option which worked, now all works well.Brew did not work, no idea why. Thank you.
